gftool.cpa.gf_cmpt_z

gftool.cpa.gf_cmpt_z(z, self_cpa_z, e_onsite, hilbert_trafo: Callable[[complex], complex])

Green’s function for the components embedded in self_cpa_z.

Parameters:

z, self_cpa_z(…) complex np.ndarray

Frequency points and corresponding CPA self-energy.

e_onsite(…, N_cmpt) float of complex np.ndarray

On-site energy of the components. This can also include a local frequency dependent self-energy of the component sites.

hilbert_trafoCallable[[complex], complex]

Hilbert transformation of the lattice to calculate the coherent Green’s function.

Returns:

(…, N_cmpt) complex np.ndarray

The Green’s function of the components embedded in self_cpa_z.
